Definitions

  • the invention relates to a method for categorizing packages for loading a terminal, for example a shipping container.
  • a method for categorizing packages for loading a terminal for example a shipping container.
  • Such a method with the features of the preamble of claim 1 is from EP 2 686 260 B1 known.
  • the packages to be transported sometimes differ significantly from one another in terms of their dimensions, volume, weight and other physical properties. Although it is part of the prior art to already measure the packages to be sorted on the previously mentioned sorter with regard to the mentioned properties, the filling of the forwarding container is still associated with considerable uncertainties. For example, when loading the shipping container with a bulky package, the package can fall so unfavorably into the shipping container that it jams in the shipping container or at least blocks a volume that is many times its own volume. It is therefore not foreseeable what number or what volume of individual packages can be accommodated in the shipping container for an optimal, at least approximately 100% filling if they are loaded individually or in bulk into the shipping container. As a result, the forwarding containers are either accidentally overloaded or often only incompletely filled due to the consideration of a buffer to avoid overloading.
  • packages that are already damaged or easily damaged due to their packaging or other external properties can be damaged further due to the small footprint of the shipping container in comparison to the height, for example if they are placed in the shipping container early and are therefore further down in the shipping container, so that still many layers of possibly heavy packages are loaded onto the damaged or easily damaged package.
  • Capturing the at least one object-specific information can include capturing a volume, a shape, or a weight and at least one other object-specific information of the respective package. Then, during the categorization, at least one weighting factor can be determined from the at least one further object-specific information, which is applied to the volume, the shape, or the weight, with a weighted volume, a weighted shape, or a weighted weight of the respective package being obtained.
  • an expected packaging volume of the package can be taken into account in one embodiment of the invention, which the package occupies when it is loaded into the shipping container.
  • This expected package volume can depend on various properties of the package and surrounding packages. For example, reduced mechanical strength of the package can result in compression of the package when the package is placed further down in the terminal and is being compressed by packages lying above and their weight.
  • the dimensions of a package can give an indication of how much volume the package will have in the final destination, such as in a shipping container, e.g. B. in a roll container, is expected to take up, in particular the volume going beyond its own volume, which can be significantly increased, for example, due to a geometry that deviates greatly from the cube shape.
  • comparatively elongated and therefore bulky objects of high strength such as parcels packed in cardboard, can occupy a volume that is many times their own volume when loaded into the terminal.
  • several of the aforementioned object-specific information can also be taken into account in the categorization and the determination of the at least one weighting factor.
  • a terminal within the meaning of the invention is not limited to any particular embodiment.
  • a terminal within the meaning of the invention can be, for example, a sorting terminal that is set up to be reloaded onto a shipping container, for example a roll container.
  • a terminal within the meaning of the invention can also be the shipping container already mentioned or a roll container. If in the following reference is made to a terminal, a sorting terminal, a shipping container, a roll container or the like, each of the specified embodiments should be included.
  • the categorizing can include sorting the packages to one of at least two separate sorting terminals, which are reloaded into the forwarding container in a loading sequence.
  • the sorting terminals can be used as intermediate buffers in order to separate the packages from one another according to at least one sorting criterion before loading them into the forwarding container.
  • the sorting criterion can be a sorting criterion derived from the object-specific information and preferably from the at least one further object-specific information. For example, light packages can be separated from heavy packages. Alternatively or additionally, large packages can be separated from small packages. Still alternatively, fixed packets can be separated from compressible packets. Value ranges can be specified for the aforementioned sorting criteria.
  • the reloading of the packages can have the ejection of the packages from at least one of the sorting terminals on a discharge conveyor between the Sorting end points and a loading station for forwarding containers is performed.
  • the sorting end points can be loaded directly into the shipping container.
  • the sorting end points can be emptied by tipping into the forwarding container.
  • the at least two sorting terminals can be reloaded into the shipping container in the loading sequence after the sum of the weighted volumes of the packages sorted to the sorting terminals has reached a capacity of the shipping container.
  • the sum of the weighted volumes exceeds the capacity of the shipping container. This can be useful, for example, if it is to be expected that additional compression of soft packages, such as foil bags, will take place as a result of the reloading of the sorting end points into the forwarding container.
  • the fixed objects also have a total weight that leads to additional compression of the soft packages results when the latter are first loaded into the shipping container and then the heavy, solid objects are loaded onto the soft objects.
  • the soft objects are loaded onto the heavy, solid objects, whereby the increase in the capacity of the shipping container achieved in the variant described above is not achieved due to the compression of the soft objects.
  • an increase in the capacity when loading the soft objects onto the heavy, solid objects can be achieved in that the soft objects penetrate into spaces between the heavy, solid objects due to their comparatively higher flexibility and thus occupy empty spaces between the heavy, solid objects .
  • Capturing the at least one piece of item-specific information may include creating an image of the package.
  • the categorization can involve comparing the generated image with images in a database, each of which is assigned at least one category. When comparing the image with the images in the database, that image in the database can be determined between which there is the smallest deviation in comparison to the image.
  • the determination of Deviation can include, for example, adjusting a distance between a surface of a filling volume in the shipping container and a top edge of the shipping container.
  • the method can also include storing the generated image in the database.
  • the image can be assigned at least that at least one category which, during the comparison, is assigned to that image in the database which has the smallest deviation from the image.
  • the acquisition of the at least one piece of object-specific information comprises the acquisition of volume-independent object-specific information, preferably the acquisition of a weight, damage, a shape, a strength, or a source of danger.
  • the determination of a volume-independent, object-specific information can be used, for example, to sort out packages which are either not suitable for loading into a shipping container due to the recorded volume-independent, object-specific information, for example because they have a source of danger or are damaged, or due to a other property counteract the goal underlying the invention, to achieve the most effective possible utilization of the shipping container, such as packages that are oversized or bulky, or are unsuitable for the automated loading of the shipping container.
  • the detection of at least one piece of object-specific information can include the detection of at least one mechanical property for at least a portion of the plurality of packages, with the categorization also taking place on the basis of the mechanical property.
  • a mechanical, object-specific property of the packages to be loaded can thus continue to be taken into account for the optimization of the loading of the forwarding container.
  • the forwarding container is first loaded with foil bags or other soft packaging units, assuming that these will not be compressed during further loading of the forwarding container, for example with packages that have a comparatively hard outer cardboard packaging and are therefore not compressed during transport are to be further compressed and thus a better utilization of the capacity of the forwarding container for receiving additional packages is available.
  • heavy packages are considered to be the compression of the soft packets, but potentially lead to major soft packet corruption.
  • the categorizing may be set up to separate packages, such as soft packages, which could potentially be subject to damage when loaded into the terminal or shipping container, from more robust packages, such as packages packed in boxes.
  • packages can be loaded into the terminal or the forwarding container in a preferred order, with the packages identified during categorization as easily damaged packages preferably being loaded into the terminal or the forwarding container after the other packages, particularly robust packages.
  • the detection of the mechanical property can also include the detection of damage to the package or an outer packaging of the package, so that the damaged packages are last filled into the forwarding container and are thus spared the weight-related stress on packages lying above them.
  • a category of damaged packages and/or a category of soft, compressible packages and/or a category of packages packed in rectangular boxes can be provided for prioritizing the packages.
  • Determining a loading sequence can be aimed at determining a suitable sequence for loading the packages into the forwarding container, depending on the mechanical properties associated with the category, which promises the most complete possible loading of the packages previously assigned to the categories into the forwarding container.
  • the parcels of the same category can be temporarily stored in a sorting terminal after categorization and before loading the forwarding container.
  • the packages can be buffered on the sorter until a combination of packages from the different categories has been determined and categorized on the sorter, which promise the most efficient possible, ie preferably the most complete possible, filling of the forwarding container, taking into account the specific loading sequence.
  • the detection of the at least one mechanical property can include the detection of the strength and/or the completeness of the package or packaging of the package. This may include detecting tears and/or other irregularities or damage to a packaging of the package in question.
  • the packets can be fed into a rotary sorter for capturing the at least one object-specific information, preferably in a flat sorter, a pocket sorter or a combined flat and pocket sorter, with the at least one object-specific information being captured while the packets are being transported in the rotary sorter .
  • the object-specific information can also be detected outside of the circulating sorter, for example when it is introduced into the circulating sorter.
  • the object-specific information can also be or have item master data.
  • the at least one mechanical property is preferably detected without contact, particularly preferably optically and, in a very particularly preferred embodiment, camera-based and with the aid of digital image processing, for example including edge detection.
  • the strength of the package or an outer packaging of the package can be inferred with a sufficiently high degree of accuracy based on the geometry of the package.
  • stronger cartons have an essentially cuboid geometry
  • softer packages such as the foil bags already mentioned, have a polyhedral geometry, which can be easily distinguished, for example camera-based, with the help of image processing methods known in the prior art.
  • the categorization can involve the ejection of the packages into one of a plurality of sorting terminals, with each sorting terminal being assigned one of the categories.
  • the loading of the shipping container can have the emptying of the sorting end points in the loading sequence in the shipping container.
  • the detection of the at least one mechanical property can include the detection of a respective strength of the multiplicity of packages or of a respective outer casing or outer packaging of the multiplicity of packages, with the packages being divided into one of at least two categories of different strength ranges during the categorization.
  • the packages can be divided into packages with a reversibly deformable outer packaging and those without a reversibly deformable outer packaging.
  • At least one further property from the group of weight, volume and dimensions can be recorded for at least some of the packages of the multiplicity of packages. For example, when categorizing the packages that have been assigned to the category of packages without reversibly deformable outer packaging, an average density can be assigned from the volume and the weight, which can be used to calculate an expected compression of the packages that is used in the categorization of the Category reversibly deformable packages were assigned, derive when first the reversibly deformable packages are filled into the shipping container when loading the shipping container in the loading sequence and then the packages are loaded onto the deformable packages without reversibly deformable outer packaging.
  • the at least one further property from the group of weight, volume and dimensions can be detected at least for those packages of the plurality of packages for which the strength of their respective outer casing or outer packaging was detected when the at least one mechanical property was detected.
  • the packets can each be divided into one of at least two categories with different strength ranges.
  • the packets of the category of a first strength range can be loaded into the forwarding container before the packets of the category of a second strength range that is higher than the first strength range.
  • this allows the shipping container to be loaded with a larger quantity of packages in terms of number and/or volume.
  • the stream loading sequence can also be reversed if the best possible guarantee of damage-free transport of the packages is prioritized over maximum utilization of the loaded volume of the forwarding container.
  • a first total volume of packages of the first category and a second total volume of packages of the second category loaded into the shipping container in the loading order can be determined on the packages of the second category.
  • the method can include introducing the plurality of packages and preferably other packages that are to be loaded into another forwarding container into the sorter before the detection, with the packages being buffered in the sorter and only then in the loading sequence, preferably directly, into the forwarding container be loaded if the loading of the large number of packages can be expected to completely load the forwarding container.
  • the use of sorting terminals for buffering the categorized packets can be dispensed with. Instead, the sorter itself can be used as a buffer.
  • a pocket sorter can be used for buffering, in which the categorized packages are ejected from the sorter, for example a cross-belt sorter, onto which the packages have previously been introduced, in order to query them in the loading sequence from a pocket sorter buffer if the forwarding container is to be loaded in the loading sequence.
  • the full loading of the shipping container can be expected when the number of packages intended for loading the shipping container, taking into account an expected packing density for the specific loading sequence, has a filling volume that corresponds to or at least comes close to a capacity of the shipping container.
  • a loading status can be detected, it being preferably detected whether the shipping container is empty. In this way it can be ensured that the forwarding container does not contain any packages or other shipments prior to loading that do not belong to the batch of those packages that are subsequently loaded into the forwarding container.
  • the detection of at least one piece of object-specific information can include the detection of damage to at least one of the packages, preferably an outer cover or outer packaging of the package.
  • the package in question can be assigned to a category for damaged packages when categorizing.
  • the packages of the category for damaged packages are preferably assigned to an end position in the loading sequence and are thus loaded last into the forwarding container. This can ensure that the corrupted packages are not further corrupted due to further stress and compression from overlying packages.
  • sensory, for example optical, detection of the loading status of at least one sorting terminal can be carried out, into which packages of the same category are presorted for each sorting terminal. This can be done camera-based, for example.
  • the packing behavior of the packets of the same category buffered in the sorting terminals can be recorded. Based on the packing behavior that occurs in the sorting terminal, conclusions can be drawn about the packing behavior of the packages in question when they are reloaded from the sorting terminal into the shipping container when the shipping container is loaded.
  • the sensory detection of the loading status can also take place exclusively at a final end point, for example a forwarding container, such as a roll container, in order to reduce the number of measuring points and thus the technical complexity of the system.
  • the method may include continuously or iteratively adapting an algorithm for categorizing the packets.
  • the smallest deviation detected during the adjustment can be minimized by varying the weighting factor and using a varied weighting factor obtained in the process in a further categorization step of a further packet.
  • Adjusting the Algorithm for categorizing the packets is preferably done using machine learning.
  • the figure 1 shows an exemplary embodiment of a sorter 2 for carrying out the method according to the invention.
  • the sorter 2 is designed as a cross-belt sorter, which forms a circulating transport loop, for example, and has at least one feed for packages 1 to be sorted.
  • the packets 1 on the sorter 2 can be detected and categorized by sensors. For example, in addition to sender and address data, physical properties of the package can also be recorded, for example dimensions and the weight of package 1.
  • the mechanical property can be a strength of the package or an outer packaging of the package 1, for example. Accordingly, when categorizing the packages 1 based on the object-specific information, a distinction can be made according to the strength of the packages 1, for example, packages 1 that have essentially solid (cardboard) packaging can be differentiated from packages 1 that are present, for example, in foil bags.
  • the packages 1 of different categories can be pre-sorted into different sorting terminals 3 for the categorization.
  • a loading status of the sorting end points 3 can be detected with a camera system 4 above the sorting end points 3 .

  • the figure 2 shows a loading tower 5 for loading a shipping container 100, which has a camera system 6 at its upper end, which is set up to detect the filling status of the shipping container 100 before the shipping container 100 is filled, in particular whether the shipping container still contains consignments of a previous sorting process are present, or whether the forwarding container 100 is completely empty and is therefore available for loading with packages 1.
  • the camera system 6 can also be provided outside of the loading tower, so that the forwarding containers 100 to be loaded are already checked for their complete emptying before entering the loading tower 5 .
  • the loading sequence can be recorded for at least some of the plurality of packages 1, taking into account the at least one mechanical property.
  • At least two of the categories or the packages 1 assigned to the categories can differ in at least one mechanical property.
  • the packets 1 in a first category can have greater strength than the packets 1 in a second category.

  • the packages 1 with the soft packaging are loaded into the shipping container 100 before the packages 1 of the category of packages 1 with hard packaging.
  • the loading of the packages 1 with rigid packaging on top of the packages 1 with soft packaging leads to a compression of the packages 1 with soft packaging and thus a densification of the packages 1 with soft packaging, thereby reducing the number of in the forwarding container 100 packets ingested.
  • the pouring and packing behavior of the packets 1 with solid packaging in the sorting terminal 3 can be used to draw conclusions about the pouring and packing behavior of the packets 1 in the forwarding container when they are reloaded into the forwarding container 100 .

  • the packing volume of the package 1 can depend on its dimensions, its strength and/or other object-specific properties.
  • a soft package 1 for example a foil bag, can have a packing volume that is significantly smaller than its actual volume. It can thus be taken into account that soft packages 1 can, for example, take up spaces between solid and/or cuboid packages when being loaded into the forwarding container 100 and thus actually and in borderline cases do not even take up any additional volume.

For example, it can be seen that the proportion of small and/or compressing packets 1 can be increased when there is a certain proportion of bulky packets 1 forming spaces which were the small and compressed packets 1 can fill. This can result in the weighting factor of smaller and/or compressible packets 1 being further reduced.
